Mine is still in bits but im having a clear out over xmas so will have another go at it but suspect it will beyond my knowledge...
Just seen this lol.
Still have the machine, unfixed in my shed.
For reference R202 is the same as R201 100ohm 7W.
Sanrex USA suggested that if PHC 101/102 were gone it was likely an indepth repair and a new PCB would be more cost effective.
Unfortunately i have no way to verify if these are...
